SPRING-SUPPORT FOR MOTO BVEHICLEF Specification of Letters Patent.

Patented Sept. 11 1917.

Application filed April 9, 1917. Bcrial No. 160,138?v T '0 all whom it may concern:

Be it known that I, CLARENCE (l Gns'r, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Spring-Support of which the following is a specification, reference being bad to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to supports that are designed to he applied to axles of motor vehicles', more especially to passenger automobiles, to support additional. springs when it is desired to haul an unusual load or in case it is desired to convert a passenger automobile into a freight truck, the invention having reference more particularly to a springsupport that is adapted to be secured to the inclosing casing of a rear axle as commonly constructed for passenger automobiles.

An object of the invention is to provide a sim 1e and inexpensive springsupport of the shove-mentioned character that shall be so constructed as to permit it to be readily applied to the :irc asing without it being necessary to rem ."1 1- the automobile wheels or disconnect any of the parts of the automooile structure, when additional springs are required or desired.

the aceompanyin With the above-mentioned and other oh- ]ccts in View, the invention consists in the novel construction in sprmg-supports and in the parts and novel oomlfdnations and arrangements 03. parts as hereinafter particularly described and further defined in claims. Referring to t e drawings,--Figure 1 is a-fragmentary side elevation of a motor truck equipped with the invention, the nearer one of the rear wheels bei brolren away to expose various elements 0 the my provement; Fig. 2 is a fragmentary longitudinal section of the rear axle casing huving* the improved spring-support applled thereto; Fig. 3 is a transverse section of the axle casing and the improved sp ringsupport shown thereon in ielevation; ig. 4 is a top plan of the main. part of the springsupport; Fi 5 is a section on the line V-V on F 4-, T ig. 6 is a perspective view of one 0 th "one for connect ng frame to .hetrnck springs; F1 7 is a central section of a clamp part 0 the springsupport; and, Fig. 8 1.811- rear elevation of for Motor Vchioles, v

- them, th

casing the truck Fig. 1 showing the pair of spring-supports re uired.

imilar reference characters on the dif fcrent figures of the drawings indicate corresponding elements or features of construetion herein referred to.

Parts of an automobile of the common type are illustrated in order to an understanding of the invention and comprise rear wheels 1 and 2, a rear axle casing compriB- ing tubular end portions 3 and 4 and a gear casing 5, elongated collars 6 and 7 bein secured to the end portions respectively an having flanges 8 and 9 thereon respectively that. are arranged adjacent to the wheels or to the brake drums usually provided. The flan es have cars 10 and 11 thereon. 1-espective y which support links 12 and 13 respectively that support the single ring 14 with which the passenger autom ile is commonly provided and on which. the frame 15 is secured. The frame may be that of the automobile as originally constructed or may be an extension thereof more particularl adapted for servin as a iart of a true platform or body. hen additional springs are required it is an important advantage to apply them without disturbing the spring 14 or interfering with its functions, more particularly to permit of ready removal of the spring-supports in case it is desired. to operate the vehicle subsequently with the springs originally provided.

Two of the improved spring-supports are provided for each vehicle and they comprise saddles 16 and. 16' that have concave under faces adapted to neatly fit 11 on the casing portions 3 and 4 respective one saddle aving two illars 17 and 18 thereon that are integral t. erewith and spaced apart sufficientlv to receive the s ring 14 between e other saddle having similar illars 17 and 18 fixed thereon. One sad 1e has apertured cars 19 and 20 thereon, the re maining saddle havin similar cars 19' and 20 thereon. The so, dles may be placed upon the axle casing adjacent to the gear 5 who're the pillars may pass under the spring 14, after which the saddles may be freely moved outward to the collars 6 and 7 respectively with the end portions of the spring 14 between the pillars of the respective saddles. Each saddle has a relatively lar e portion 21 to clear the cwllar 6 or 7 and a so has a. reinforcing b 2. on its lars. Also the saddles preferably have bearing projections 23 and 23 integral therewith respectively that extend beyond the saddles along the casing portions 3 and 4 respectively to serve as stay braces for the pillars and provide ample bearing surface upon the ordinarily thin wall of the axle casing. Two clamp parts '24 and 24 are provided which have concave faces adapted to bear against the under side oi the Casi 11g portions 3 and 4 respectively, cat-h clamp part having apcrturcd cars 25 and 26 thereon respectiv ly \vliirh are secured by means of bolts and in. to the ears of the saddle that is rr' gm above the clamp part. Each .i .p pail has relatively large portion 29 to receive the end portion of the collars (i or 7 and has also an external strengthening rih 3O thereon. The clamp parts are provided on the larger portions 29 thereof with cars 31 and 31' IGSIWCtiVRly to which a truss rod 32 connected in means of nuts 33 and 33, the truss rod being drawn into contact with the iillllUI' portion of the gear case The pillars l7 and 18 have reinforcing ribs 54 and 341 on the outer sides thereof that extend to lh cars 19 and 20, the pillars IT and 18 having similar ribs 3-1 and 35 thereon respectiveh-n The upper portions of the pillars 17 and 18 have 'flat spring seat plates 36 and 37 integrally fixed thereon re spectively that are supported upon the tops of the adjacent ribs 34 and 35, the pillars 17 and 1S and the adjacent ribs having similar plates 36 and thereon. The two I) spring-supports are identically alike but are arranged in reverse order on the axle casing. Two seinielliotic springs 38 and 33, \vl'ich are idcnticall v alike are pr0- ille-1i, the mi ldle portirri of one spring be ing seated upon the spring seat plates of mm pair or pillars, the rcmainin spring he '1 no s ten risimilarly upon the lil e plates of pair oi pillars. The spring, seat suitably apertured to receive clips a Y of tamiliar construction, two yokes i-1 being employed to secure one spring upon its seats, similar yokes or clips 39' being employed to secure the remaining spring in place. Links 40 and 41 are connected to the opposite ends respectively of. each pring 38 and 38 and have arms 42 and 43 connected thereto respectively which are secured to the frame 15, the springs augment-- ing the power of the spring 14 to support the load which. may be placed upon the frame.

In practical the additional springs 38 and 38' not only enable the frame 15 to carry relatively heavier loads than formerly, but tend to preventexcessive tilting of the frame 15 upon the middle portion of the spring 14. By the use of the improved spring-supports and the auxiliary springs, a passenfier automobile after having become undesira le from long use for passenger service, may be economically converted into a truck with little expense and its usefulness thus extended.

Having thus described the invention, what is claimed as new is-- l. A spring-support comprising a curved saddle having two spaced'apart spring-supporting pillars integral with the convex side thereof and also a transverse rib integral with the convex side and also with [he two pillars, a curved clamp part, and bolts for connecting the clamp part with the saddle.

:2. A spring-support comprising a saddle having two pillars integral with the normal upper side thereof in spaced relation, the under side of the saddle being concave, the top of each pillar having a spring-seat plate integral thereon, a curved clamp part, and bolts for connecting the clamp part with the saddle.

A springsupport comprising a saddle having two pillars integral with the upper side thereof. the under side of the saddle being concave and having one relative]; larger spanning end portion, the opposite end of the saddle having a projection integral with the middle portion. thereof, two nillars integral with the saddle, each pillar having a spring-seat plate thereon, a clamp part, and bolts for connecting the clamp part with the saddle.

4:. A spring'support comprising a saddle having a concave underside and apertured ears on the opposite sides of the concave portion, two pillars integral with the opposite under side of the saddle. each pillar having :1 rnw..,r-seat "plate integral with the top lthcroo-r and having also an integral rib extending: from said plate to the adiacent one of said cars. a clamp part, and bolts for connecting the clamp part with the ears of the saddle.

5. In a springsupport for motor vehicles, the combination with an axle casing, of a saddle seated upon and extending continuously across the top of the casing, said saddle having two integral therewith in spaced apart relation, and a clamp part. arranged beneath the axle casing and connected to said. saddle, said clamp part having an ear thereon to receive a truss-rod.

In testimonv whereof, I affix my signature in presence of two witnesses.
